It plugs into the car so it turns on when the car does and starts recording when set parameters are met. Like I can program it to start recording when the car goes over 20mph. Or whatever I want. Also I never have to worry about losing video to a dead battery, AND my videos will have a video game style HUD, with RPM, speed, gear, lap times, and even a track map! It wasn’t cheap but I think it’s totally worth it.

Also it makes me uncomfortable how much bigger my images are than everyone else’s.
